An account correction should preserve the original instruction, the reason for changing it and the evidence supporting the reviewer’s decision.

What the primary record establishes

Rule 4515 requires principal authorisation and written supporting facts for account-designation changes. Pre-execution changes require approval and documentation before execution. FINRA Rule 4515 — Changes in Account Name or Designation ↗

Its investment-adviser allocation exception has defined conditions; it is not a general permission to assign every trade later. FINRA Rule 4515 — Changes in Account Name or Designation ↗

What the distinction changes

WFN interpretation: a correction is an operational event with its own history. Overwriting the account field can make a later report look tidy while removing the evidence needed to explain how the final assignment arose.

A reviewable record links the original designation, proposed replacement, reason, supporting material and approval. The timing of each step helps distinguish a genuine correction from an unexplained reassignment.

What to check before drawing a conclusion

For workflows involving advisers, check the exception against the actual order and account population. A firm should not treat the existence of any adviser relationship as sufficient evidence that the exception applies.
